CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 387,584, dated August 7, 1888.

Application filed January 7. 1888. Serial No. 260,033. (No model.)

. To all whom it may concern.-

Be it known that I, Bonner H. BOWLING, a citizen of the United States, residing at New ark, in the county ofLic-king and State of Ohio, have invented certain new and useful Improvements in Car Couplings; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters 0r figures of reference marked thereon, which form a part of this specification.

Figure 1 of the drawings is a front View of the invention. Fig. 2 is a top view. Fig. 3 is a side view. Figs. 4 and 5 are sectional views of the draw-head. Fig. 6 is a sectional view of the drawhead, showing the movable jaw. Figs. 7', 8, 9, 10, 11, 12, and 13 are detail views. Fig. 14 is a detail perspective showing the shoulders ff.

The invention relates to ear couplings; and it consists in the construction and novel combination of parts, as hereinafter set forth.

Referring to the drawings, A designates the end sill of a car provided with the usual bearings and buffers for the shank of the drawhead 13.

At one side the draw head B is provided with the integral forwardly-extending projection a, and upon its opposite side extend the bearing-lugsa. Theouter wall or portion, 1), of the draw-head adj acent to the lugs a extends forward to a point longitudinally opposite the bearingopenings b in the lugs. The front face, 0, of the draw-head B is horizontally of a general concave form. The inner edges of the lugs 64, however, project toward the vertical center of the face 0. A recess, 0, formed in the draw-head, extends from the wall b nearly across the face 0, as shown. Its vertical wall d describes nearly the are of a circle. The wall (I of the recess 0 is vertically recessed, as shown at d, said recess (1 registering with an upward and outward opening, 0, and oppositely connecting at one side with the downward opening 0. The openings 0 c and the recess (1 are for the accommodation of a fiat locking-key, hereinafter described. The lugs a are segmentally thickened, as shown, to form the shoulders f f, and shoulders g are provided at a portion of the circumference of the lugs.

'0 is the movable jaw or coupling-hook, having the shank portion h, standing at nearly right angles thereto, and the bearing-block h. The bearing-block h is designed to turn between the lugs a, and the shank h moves in the recess 0. The outer ends of the bearingblock h are transversely shouldered, as shown 6c at z. XVhen the movable jaw is in a closed or locked position, the shoulders t are brought in contact with the shoulders fol the lugs, and the projections t" of the bearing-block impinge upon the shoulders 9, thus relieving the pivotal bearing of the block 0 from pressure inwardly during the operation of connecting the cars. The shoulders f of the lugs are designed, by coming in contact with a portion of the shoulders g, to prevent the movable jaw from opening too far.

The bearing-block Ois provided with alongitudinal opening, it, registering with openings b in the lugs a, and through said openings 70 b a pin, D, is passed, pivotally turning in the openings 1).

E represents the locking-key, the upper section of which is adapted to the size of the opening 6 and the recess (1, and the lower portionis made narrower in cross-section to fit the opening 6 through which it passes, extending normally below the lower face of the draw-head B, where it may be provided with a ring or pin-stop, .e. The upper section of the locking-key E is thickened and provided with the inclined shoulder Z, projecting beyond the recess d. When the movable jaw G is opened, the outer edge, Z, of the shank It stands outwardly from the plane of the face of the draw-head to receive the pressure of the coupo ling of an approaching car. As the couplings come in contact, the shank h is forced into the recess 0, closing the jaw G, and thus forming a coupling. As the shank h passes inward, its end bears against the inclined shoulder Z, pushing the key upwardly until the projection at of the shank passes to the opposite side of the key. The key then drops and locks the jaw O in a closed position.

The pin D is provided on one side with a [00 guard, a, and the opening it is recessed at one side to engage the guard a, which prevents the jaw from turning on the pin, the pin turning in the openings Z) of the lugs, one ofsaid openings having the radial notch n to allow the pin and guard to be inserted. One end of the pin D projects through the lugopening, and is provided with a retainingpin, 0, which passes through a transverse opening near the end oi" the pin. The opposite end of the pin D extends through the lng-bearing and is turned to form the crank 0, standing at right angles to the pin.

An opcratingrod, F, is pivotally connected to the crank o, and extends outwardly to the side of the car, where it is provided with a handle, 1). An eyebolt, p, or other suitable bearing is secured to the end sill through which the rod F passes.

G is a bar for operating the locking-key E; The bar G has the slot-opening r near its center, through which a pivot-bolt, 1", passes. This pivotal connection allows the bar G to be worked longitudinally and as a lifting-lever. The inner end of the bar G is turned outward to engage in the transverse opening t in the key E. This outwardly-turned portion extends some distance beyond the key, so as not to become disengaged when the drawhead is pulled outward by strain. The outer end of the bar G is turned at right angles to form a handle, t, and near the handle t a re taining-pin, v, is seated in the sill A. By this arrangement of working-levers the operatoris not required to place himself between the ears while coupling. The operator stands at the side of the ear, grasping the handle of the bar G with one hand and the handle otthe rod F with the other hand, and to place the coupling es a es underneath the retaining-pin e, securing the bar. 13y pushing the rod F inwardly it operates on the crank 0, thus opening the jaw. The key may then be lowered, and the approaching drawhead automatically closes and locks the jaw.

The movable jaw at its outer end is centrally cutaway and provided with the pin-hole w, in order that the ordinary link and coup li ngpin may be used when necessary. An integral projection, 1 in the upper side of the d raw-hcad is designed to strike against a butfer.

Having described my invention, what I claim 1s- 1. In a coupling, the combination of the draw-head having the recess, the movable jaw having the shank provided with the projection m, the pin D, having the crank portion and the guard n, the flat lockingkey having the inclined shoulder, the transverse slot, and the retaining-pin at, substantially as specified.

2. The combination of the draw-head having the hearing-lugs, the segmental shoulders thereon, and the shoulders g, the recesses c d, the openings 0 e, the key E, having the inclined shoulder and the stop m, the movable jaw having the shank portion provided with the projection, and the bearing-block having the transverse shoulder, the locking-key having the shoulder and the transverse slot, the pin provided with aguard and crank portion, and the operating levers, substantially as specified.

In testimony whereof I atlix my signature in presence of two witnesses.
